The focus is performance nutrition. Resistance exercise can induce low level muscle damage in conjunction with impaired contractile function. Milk-derived proteins contain, or induce, bioactive properties that assist muscle recovery and restore/improve muscle function. The aim of the research is the recovery of muscle function following resistance exercise.

In this study, the investigators propose to undertake a comparison of the ingestion of two milk-derived protein-based recovery drinks on muscle function after resistance exercise compares to an isonitrogenous, non-essential amino acid control.

Muscle Contractile Function to be conducted prior to and following the RET session by laboratory-based ergometry. Muscle Protein Synthesis induced by RET to be measured by deuterium incorporation in to skeletal muscle sampled by microbiopsy.

Dietary Supplement: Whey Protein Concentrate

Whey protein concentrate in powdered form, flavoured and instantised to be dissolved in water.

Dietary Supplement: Whey Protein Hydrolysate

Whey protein concentrate hydrolysate (degree of hydrolysate 27%) in powdered form, flavoured and instantised to be dissolved in water.
